Pink Fused Aluminum Oxide (FEPA F and FEPA P - Macrogrits & Microgrits)

Download: Technical Data Sheet | Safety Data Sheet (SDS)


Pink Fused Aluminum Oxide contains chromium oxide, which gives the material its pink color. The incorporation of the Cr2O3 into the Al2O3 crystal lattice produces a slight increase in toughness and a reduced friability compared with White Fused Alumina.

Compared to Brown Regular Aluminum Oxide the Pink material is harder, more aggressive and has better cutting ability. The grain shape of Pink Aluminum Oxide is sharp and angular.


The FEPA F grades are especially suitable for the manufacture of vitrified bonded abrasives for working hardened steels and alloys with tensile strengths of over 50 kg/mm². It is also used in tool grinding, saw and knife-sharpening applications, precision grinding, profile grinding, flute grinding, tooth grinding, dry grinding of blade segments and mounted wheels.

The FEPA P grades are a preferred material for working non-ferrous metals and the alloys (copper, aluminum, zinc, brass, Bronze), but also used for softer materials, such as wood, synthetics and paints.
